PAUL GROBECKER, OF ARTERN, SAXONY, GERMANY.

APPARATUS FOR TESTING GRAIN.

SPEGIFIQATEON forming part of Letters Patent No. 381,469. dated April17, 1888.

Application filed September 14, 1887. Serial No. 249,616.

(No model.) Patented in Germany November G, 1886, No. 39,622; in

England November 29, 1836, No. 15.569, and in Austria-Hungary Aprile,i887, No. 46,594 and No. 11,700.

To all whom it may concern:

Beit known that I, PAUL Gnonnciinn, of Artern, Saxony, Germany, haveinvented certain new and useful Improvements in Apparatus for TestingGrain, (for which Letters Patent have heretofore been granted to me inGermany, No. 39,622, dated November 6, 1886; in Great Britain, No.15,569, dated November 29, 1886, and in Austria-Hungary, No. 46,591 andNo. 11,700, dated April (i, 1887,) of which the following is aspecification.

The object of my invention is to provide a new and improved apparatusfor cuttinggrains transversely, so as to obtain a clean-cut crossseetionof the same to facilitate examining them.

The invention consists in the combination, with a cup or receptaclehaving tapered apertures in its bottom, of a plate hinged to the underside of said cup and provided with cor. responding apertures, and acutter pivoted between the cup and the plate.

The invention also consists in the construction and combination of partsand details, as will be fully described and set forth hereinafter, andfinally pointed out in the claims.

In the accompanying drawings, Figure 1 is alongitudinal sectionalelevation of my improved device for cutting grains, the handles beingshown in elevation and the cup and the plate being so adjusted thattheir apertures coincide. Fig. 2 is a plan view of the same, the cutteror blade being swung from below the receptacle, parts of the receptaclebeing in section. Fig. 3 is a cross-sectional view of the plate and ahinged check-plate on the under side of the same on the line x m, Fig.2. Fig. 4 is a cross sectional view on line y y, Fig. 1.

l Similar letters of reference indicate corresponding parts.

The cup-shaped receptacle a, which has a handle, a', is provided in itsbottom with aseries of apertures, a2, which are tapered from the upperto the lower surface of the bottom of the said cup-shaped vessel a. Theplate b is of the same diameter as the cup a, and is provided with ahandle, b', which is pivoted to the handle a by the pivot c, and saidplate b is provided with a series of apertures, b2, co-

inciding with the apertures of the cupa, which apertures b2 also taperfrom the upper to the lower surface of the plate b, the upper diametersof the apertures()2 being the same as the lower diameters of theapertures a?.

The handles a b are preferably made of spring metal, and the handle b isprovided at its free end with a nose, g', which can pass into the notchg2 in the bent end of the handle b' for the purpose of holding the platebin such a position in relation to the cup a that the axes of theseveral aperture a2 b2 coincide, the spring-tension ot' thehandl'eskeeping the nose g in the notch g2.

A disk-shaped blade, h, is mounted to turn on the pivot c, and to swingin between the under side of the cup a and the upper-surface of theplate b, said disk-shaped blade 7L being provided with a handle, h',arranged-between the handles a b. the edge with a downwardly-projectingscrew, e, on which a lug, d', is mounted to turn, said lug projectingdownward from a plate, d, at the edge, which plate d is provideddiametrieally opposite to the lug d' with a spring-catch, j', the freeend of which is adapted to engage a notch, f, on the plate b. The plated is also provided at its upper side with tapered apertures d2, whichcoincide with the apertures a? and b". As the lug d is mounted on thescrew e, it is evident that by turning the plate in one direction it ismoved from the under side of the plate b and by turning it in the otherdirection it is moved toward the plate Z1, thus permitting of adj ustingthe plate d at a greater or less distance from the under side of theplate b. This'is necessary, as the grains have various lengths.

The operation is as follows: The plate d is adj usted, in the manner setforth, a greater or less distance from the under side of the plate b,according to the length of the grains, and locked in place by thespringf. The blade or cutter h is swung from under the cup a into theposition shown in Fig. 2, and a quantity of grain placed in the cup a,which cup is then shaken, so that the grains pass into the apertures a2b2 d2 and stand vertically in the same. The handle h of the cutter h isthen swung in the direction of the arrow w, Fig. 2, so as to The plate bis provided at 7 IOO lwith a handle pivoted to the handle of thecupshaped vessel, which plate is also providedwith tapered apertures inline with those of the vessel, and a blade pivoted between the twohandles to swing between the upper surface of the plate and the underside of the cup-shaped vessel, substantially as shown and described.

2. The combination, with a cup-shaped vessel having tapered apertures inits bottom, of a plate pivoted to the under side of the cupshaped vesseland also provided with apertures coinciding with those in the bottom ofthe vessel, a check-plate pivoted to the under side of theabovementioned plate and also provided with tapered apertures thecenters of which coincide with those of the apertures in the other plateand the cup-shaped vessel,

. invention I have signed my name in and a blade pivoted between thecup-shaped vessel and the plate pivoted to it, substantially as shownand described. l

3. The combination,with the cup shaped vessel a, having taperedapertures a2 and the handle a', of the plate b, having tapered aperturesb2 and handle b', the pivot c, by which the handles a b are pivotedtogether, and the blade'h, mounted on the pivot c at the under side ofthe cup a, substantially as shown and described.

4. The combination, with the cupshaped vessel a, having the taperedapertures a?, of the plate b, having the tapered apertures b2, the plated, provided with the lug d, the screw e, projecting downward from theplate b, on

which plate the-lug d is mounted to turn, the

catchy, and the blade h, pivoted between the cup-shaped vessel and theplate b, substantially as shown and described.

In testimony that I claim the foregoing as my presence of twosubscribing witnesses.
